Specification of Letters Patent.

Patented Oct. 80, 1906.

Application filed April 17, 19GB. Serial No. 312,248.

To all w/wm it may concern:

Be it known that I, J ornv C. MILLER, a citiin the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Pull-Rod Couplers; and 1 do hereby declare the following to be a full, cle r, and exact description of the invention,

' such. as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pull-rod couplers that are especially adapted to be used in transmitting power from a central station to any convenient points over a specified and limited field.

The invention comprises the construction of a coupler having a supporting S-shaped member, clamps for securing the same in position, and rods pivotally mounted upon said clamping member.

The object in View is the production of a pull-rod coupler having means for pivotally securing the same to standards from above or below, as may be desired.

A further object in view is the production of means for coupling two or more couplers together for transmitting power at an angle to the main transmission of power.

A still further object of the invention is the production of an S-shaped member for mounting the coupler in place, clamping members securing the S-sha ed member in place, and ull-rods pivotal y mounted between the c amping members.

With these and other objects in view the invention comprises certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view of a system of pull r0ds and couplers embodying the features of my invention. Fig. 2 is a side elevation of the preferred form of my invention. Fig. 3 is a vertical section of a slightly-modified form of my invention, the same showing a con ling member carried by the preferred form 0 m invention. Fig. 4 is a vertical section on inc 5 5 of Fig. 5. Fig. 5 is a top plan view of the coupler embodying the features of my invention with a second coupler secured to the same and adapted to transmit motion at an angle thereto.

In oil-fields it is necessary to have means for pumping oil from the wells, and it is found very undesirable and expensive to mount an engine at each well, and therefore it is common to have a large power-engine located at a convenient point to a number of wells, so that power may be transmitted from the engine to the various wells. This is accomplished in many ways, the most common of which is through the reciprocation of pull-rods. To this form of transmission of power my invention relates, and more particularly to the coupler employed for securing together the various pull-rods and adapting the same to be placed at various angles to the main line of power transmission.

My invention is also particularly adapted to be used in oil-fields where it is necessary to transmit power over uneven surfaces, and therefore the pull-rods must be so mounted as to be supported from above when assing over small rises or held to the cart when passing through ravines and the like.

In the preferred embodiment of my invention I provide a pair of clamping members 1 and 2, which are adapted to be secured in place by any suitable means, as 3 3. To the securing means 3 3 is pivoted the horizontal ull-rods 4 4 now used in most oil-fields.

.Iounted between the pull-rods 4 4 is an approximately S-shaped member 5, which is preferably made from bar metal bent into the desired shape. The ends of the S- shaped member 5 are closed, so as to form ring-shaped portions 6 and 7.

In use the pull-rod coupler is mounted either on a supporting means, as the tripod 8, or the restraining-rod 9 by means of the S-shaped member 5. A hook or eye portion 10 is passed through the ring portion 6 of the member 5 and securely holds the coupler in position, but permits the same to oscillate, as may be desired.

In 0 oration it is often desirable that power s ould be transmitted from the main transmission-line at a sli ht angle, and in order to accom lish this I mount a second coupler, as 11, elow the coupler 12 on the main power-line. In mounting a second coupler on the main cou ler 12 in order to.

transmit power at an ang e thereto I preferably remove the S-shaped member 5, as will be clearly seen in Fig. 3 of the drawings. The main line may be connected to a umping device 14, if desirable, and the side ine to another similar device, as 15, or, if preferable, both or either lines may be used to drive any other machine which a reciprocating motion will operate. In case power is desired BEST AVAILABLE COPY to be transmitted at more than one angle at a single mission hne the S-shaped mem er is left in position, as seen in Fig. 5, and the pull-rod secured to the ring-shaped member 6 or 7, as

Ias on a pendulum, to prevent the power from drawing the rod down or may be anchored to the ground to prevent the )OW'BI' from raising the pull-rod too high in t e air with equal adaptability.

Vhat I claim is 1. A pull-rod coupler comprising clamping members, means for securing the same toegther, and a substantial S-shaped member secured between the said clamping members for holding the pull-rod in position.

2. A pull-rod coupler comprising clamping members, pull-rods pivotally mounted there in, and means having looped ends loosely point along the main ower-trans-' mounted between said clamping membg for securing the said oupler in position.

3. A pull-rod coupler comprising clampi members, means or pivotally mounti: pull-rods between the same, and an S-shap supporting member secured between sa clamping members.

4. A pull-rod coupler comprising side mer bers, means for securing the same togethe means positioned between said side mei bers for holding the same in operative poi tion, a loop formed integral with said su taining means and a second coupler pos tioned at an angle to the said coupler, ar sustained in position by said loop.

5. A pull-rod coupler com rising clampir members, means for pivotal y mounting tl pull-rods therebetween, and an S-shape member mounted between said pull-rec and said clamping means and having ti loops projecting above and below said clam} ing means, the upper loop of said S-shape member sustaimng the coupler in positio and lower loop accommodating a pull-r0 positioned at an angle to said coupler.

In testimony whereof I aliix my signatur in presence of two witnesses.
